Abstract

On décrit un dispositif à deux connecteurs utilisé pour fournir à un appareil de l'énergie électrique provenant de plusieurs sources de puissance présentant des géométries de prise de courant différentes. Le dispositif à deux connecteurs comprend des premier et deuxième connecteurs mobiles pivotants comportant chacun un contact électrique pouvant se loger dans des premier et deuxième contacts respectifs d'un appareil et pouvant également sortir de ces derniers ainsi qu'un mécanisme de commande qui n'autorise qu'un seul des connecteurs à pivoter pour se loger dans un contact correspondant à un moment donné, ceci permettant à un seul des connecteurs de transporter du courant électrique à un moment donné. Le mécanisme de commande peut comprendre des première et deuxième cames qui sont respectivement attachées au premier et deuxième connecteurs et un suiveur de cames placé de manière à coulisser entre ces derniers. Les premier et deuxième connecteurs peuvent comporter un dispositif de connexion du type norme américaine/norme européenne et un dispositif de connexion correspondant à la norme du Royaume-Uni, un connecteur à deux broches et un connecteur à trois broches, deux broches polarisées ou tout autre type de dispositif de connexion ou de connecteur permettant à l'utilisateur d'effectuer le raccordement. Le dispositif à deux connecteurs peut être attaché à un ensemble chargeur et source de puissance destiné à un appareil électrique comprenant un bloc-batterie amovible ou peut être utilisé sur une rallonge ou directement sur le cordon d'alimentation d'un appareil électrique.
